Method and apparatus for finding social connections based on concealed movement trajectories

摘要

A method for finding social connections between users based on concealed movement trajectories is provided. In one method, the concealment area of the first movement trajectory of the first user and the concealment area of the second movement trajectory of the second user are each converted into corresponding semantic areas, which are corresponding concealment areas. Expressed by the semantic meaning of the domain. The converted semantic area is mapped to a node of the hierarchical semantic tree, and each node of the hierarchical semantic tree corresponds to a semantic area. The society of the first user and the second user according to the relationship between the node mapped to the semantic area of the first movement locus and the node mapped to the semantic area of the second movement locus. Can be guessed. [Selection] Figure 3
